CHeaderCtrl

[Robertus]

How could I change the color of a header ctrl in a listControl?

I assume you use MFC.

Derive a class from CWnd which processes WM_ERASEBKGND message:

class CHdrWnd : public CWnd
{
public:

protected:
   afx_msg BOOL OnEraseBkgnd( CDC* pDC );

   DECLARE_MESSAGE_MAP()
}

BOOL CHdrWnd::OnEraseBkgnd( CDC* pDC )
{
     pDC->FillSolidRect(RGB(255, 0, 0));//your color
     return TRUE;
}

In the class asociated with parent window of list view declare a data member of type CHdrWnd:

CHdrWnd   m_wndHdr;

Now in your WM_INITDIALOG or WM_CREATE message handler of the parent window of list view do the subclassing of the header:

....
HWND hWndHeader = (HWND)SendDlgItemMessage(IDC_LISTVIEW, LVM_GETHEADER, 0, 0);

m_wndHdr.SubclassWindow(hWndHeader);
